"Production is set to begin next month for the screens, which measure at least 4 inches diagonally compared with 3.5 inches on the iPhone 4S, the latest phone from Apple, the people said." Cue the usual suspects twisting and turning to change the very fabric of space-time so that instead of 3.5" being the optimal size, 4.0" will be the optimal size. Sit back, relax, and enjoy the show.

Have you, you know, tried to pocket a 7 inch tablet? When the original Galaxy Tab came out, I was working in a phone shop. My coworkers didn't believe me when I said it was a conveniently pocketable size, and furthermore, it would fit in their handbags a whole lot easier than an iPad. To prove my point, I put two dummy units of the Galaxy Tab (that is to say, non functional but identically sized, shaped and weighted units), and my 5 inch Dell Streak into my left pocket. My perfectly ordinary black slacks had a big enough pocket for two of them and a huge phone.
